Hoʻohana huahana:
1.Hoʻohana nui ʻia ka Valeric anhydride ma ke ʻano he reagent a me ka waena i ka synthesis organik.
2.Hiki ke hoʻohana ʻia e hoʻomākaukau i nā pūhui me nā hui hana like ʻole, e like me ka ethyl acetate, anhydride esters a me nā amides.
3.Hiki ke hoʻohana ʻia ka Valeric anhydride i ka synthesis o nā insecticides a me nā mea ʻala.
ʻIke palekana:
ʻO 1.Valeric anhydride ka mea hoʻonāukiuki a me ka corrosive, e pale i ka piliʻana me kaʻili a me nā maka a me ka mālamaʻana i ka mālamaʻana i kahi wahi maikaʻi.
2. I ka mālama ʻana a me ka mālama ʻana, e pale i ka hoʻopili ʻana me nā mea oxidizing a i ʻole nā ʻakika ikaika a me nā kumu e pale aku i nā hopena weliweli.
3.E hahai i nā kaʻina hana palekana no nā kemika i ka wā e hana ai a loaʻa iā lākou nā mea pale kūpono e like me nā mīkina lima laboratory, nā aniani palekana, etc.
